I am looking to resurrect a 96 xp that I raced against in the day but have ZERO doo knowledge.I raced Kawasaki back then and building a fast boat was so much easier......that rotory thing baffles me............Any way I bought this ski I raced against back in 96 97 and still have the ski i raced back then and thought it would be cool to take them out once in awhile to ride with my son....Problem is I have NO idea how to work on the doo. It had a dead cylinder so I pulled the motor to check things out and cant find any engine issues I am willing to spend the money but dont know where to start. My Kawi is full blown SS as per 96 IJSBA rules and would like to make the doo the same, Anyhelp / info would be awesome.
